There’s no need. You can trust that we will be there for you on time. Here’s why: we monitor the weather and keep track of your usage on a daily basis. We do this by counting “degree days.” When the weather gets colder, we make deliveries sooner. This system has proven to be 99.5% effective. A tank just one-quarter full can last a whole week for the average family of four, even when it’s zero degrees outside. That’s plenty of time for us to get to you.
